Most British wind turbines do not make much noise as they spin around making electricity and people who complain about them should not be losing sleep, according to a study published.
Some people living near wind farms complain they are kept awake by a phenomenon known as aerodynamic modulation（AM）, low frequency noise made as the blades swoosh through the night air.
A government-commissioned study by Salford University found the phenomenon -- sometimes described as sounding like a distant train -- could affect four of the country’s 133 wind farms.
This, the government says, is no justification for stemming the growth of the technology Britain is betting on to cut its carbon emissions.
"Where there are legitimate problems we will address them," Energy Minister Malcolm Wicks said in a statement. "But it is essential that we produce more wind power if we are to meet our climate change and security of supply aims."
